Salt and sugar are both dissolved in water. What are the number of components and the solvent in this mixture?
Answer and explanation
Correct answer: Three components and water solvent
A mixture’s components are the distinct substances present, whether they are dissolved or serve as the medium. Here the substances are water, salt, and sugar, so the total is three components. Water is present in the larger continuous amount and dissolves both salt and sugar; therefore it is the solvent. Salt and sugar are solutes. Hence B is correct, while A omits water and C and D wrongly call a solute the solvent.
